Attribute Value for Type Text

Arbitrary user-visible text

The Text attribute type is very similar to the CDATA attribute type, with the only difference being that the Text type is assigned to attributes which hold information intended to be visible to the viewer of the document, whereas the CDATA type is concerned with the internals of the page.

Handling Invalid Characters

Within XHTML 1.1 attribute values:

• Every less-than character (<) within an attribute value must be escaped as < (or <).
• Every ampersand character (&) which does not denote the start of an entity or character reference (e.g. <) must be escaped as & (or &).
• Every double quote character (") must be escaped as " (or ") if using double quotes to delimit the attribute value
• Every single quote character (') must be escaped as ' if using single quotes to delimit the attribute value (alternatively ' may be used if compatibility with HTML isn't necessary - see Character Entities Predefined by XML 1.0)
